[0037] The present invention will be further described in detail below in conjunction with the drawings and implementation methods.
[0038] Reference figure 1 Perform steps to illustrate the implementation process of the present invention:
[0039] Step 1, prepare the data
[0040] Step 1-1, first judge whether there is a calculation task, if so, go to step 1-2, otherwise the calculation ends;
[0041] Go to step 1-2, read system variables, and judge whether pre-tuning is specified, if yes, go to step 1-3, otherwise go to step 1-4 to format data;
[0042] Go to step 1-3 to read the recorded data of the sparse matrix in the file, perform the pre-tuning process, and write the optimal partition block size into the system in the form of environment variables. The purpose of this step is to obtain a sub-block size suitable for the current computer hardware platform through automatic tuning, and then optimize the Cache behavior;
[0043] Go to step 1-4, if the sparse matrix data is not...
